Their true colors come out! This logic came out of the UN agenda 21 initiative passed in Rio-de-Janeiro in 1992 which when one reads, along with all the rest of the ‘propaganda,’ one sees that the REAL purpose behind all of this is a major reduction in population. What is really meant by ‘sustainable’ is a world with less than one billion people powered by solar and wind which is the maxim that they think those forms of generating energy will support. Their population estimated are probably off as its more like a lot less than one billion.
